Introduction:

Any change in velocity requires a force. When this force is steady, the feeling can be compared to gravity. By controlling the rate of change of velocity, the "Gs" can be adjusted.

Activity:

• Watch the video clips at this link:
• 
• Think about the activities that you will put in the spinning ring of your Space Hotel!

Conclusion:

The curvature of the Earth is so gradual that we barely notice it. In a spinning structure, the curvature could be very noticeable!

Hint: It has to do with the windows and the "floor"!
